It’s amazing how passionate some people can be about zeroes. I have known people who hate, with a passion, to see zeroes displayed in their reports. They will sometimes use some formula acrobatics to avoid having a zero displayed.

Click the File tab and click Options
Click the round Office button (top left) and click the Excel Options button
Both Excel 2007 + 2010
Click the Advanced option on the left and scroll two thirds down and look for the section as shown in the image below. Untick the option Show a zero in cells that have a zero value and click OK.
Click the Tools menu and select Options then click the View tab and untick the Zero values option and click OK.
Now all zero cells will appear blank.
If you only want to stop zeroes displaying in a range and not the whole sheet you can use a Custom Format like.
See image below – this works in all versions
